Answer:
TRUE!!!!
Explanation:
Water can act as both an acid and a base in solution and undergoes autoionization, where it can be both an acid and a base to itself. When mixed with an acid, water accepts hydrogen ions and acts as a base. However, when water is mixed with a base, it donates hydrogen ions and acts like an acid.
Not my words! I hope this helps :)
Answer:
-4.59°C
Explanation:
Let's see the formula for freezing point depression.
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Freezing constant. For water if 1.86°C/m
m = molality (moles of solute in 1kg of solvent)
i = Van't Hoff factor.
0°C - Freezing T° of solution = 1.86°C /m . 1.30m . 1.9
Freezing T° of solution = - (1.86°C /m . 1.30m . 1.9)
Freezing T° of solution = - (1.86°C/m . 1.30m . 1.9) → -4.59°C
NaCl → Na⁺ + Cl⁻
Answer:
1.009 atm is the total pressure for the mixture
Explanation:
To determine the total pressure in atm, of the three gases (N₂, O₂ and Ar) we have to sum all the values.
Sum of partial pressures in a mixture = Total pressure
First of all, we need to convert the values from mmHg to atm
604.5 mmHg . 1atm / 760 mmHg = 0.795 atm
162.8 mmHg . 1atm / 760 mmHg = 0.213 atm
0.500 mmHg . 1atm / 760 mmHg = 6.58×10⁻⁴ atm
Partial pressure N₂ + Partial pressure O₂ + Partial pressure Ar = Total P
0.795 atm + 0.213 atm + 6.58×10⁻⁴ atm = 1.009 atm
Answer: Hydrolysis
Explanation:
ATP + H2O -----> ADP + Pi + energy
The above reaction is known as ATP hydrolysis.
The energy molecule Adenosine Triphosphate is broken down to Adenosine Diphosphate and phosphate group. Hydrolysis reaction of ATP is accompanied with the release of energy. This energy is used to perform cellular work.
Hydrolysis reaction is a Catabolic reaction
Hydrolysis: hydro -water ; Lysis means break
Hydrolysis means break a compound using water
